Application filed July 27, 1910. Serial No.. 574,103.

To all whom it may concern:

Be it known that I, FREDERICK W. AL- BRECIIT, a citizen of the UnitedStates, and a resident of rIoledo, in the county of Lucas and State ofOhio, have invented a certain new and useful Rotary-Saw Trimmer; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the aC- companying drawings, and to the figures of reference markedthereon, part of this specification. y

` My invention relates to means for use in connection with rotary sawsoi' cutters for planing the edge of work during a sawing.

operation. Y

The object of 'my invention' is the provision of 'improved planing meansof this type, which is simple and economical in its construction, andvcapable of being easily and quickly removed or inserted into posin whichextends entirely or nearly across tion .within its carrying part, thusfacilitating the substitution of one for another as one in use maybecomedull yor broken.

The invent-ion is fully described in the following specification and apreferred embodiment thereof illustrated in the accompanying drawings,in which,-

Figure 1 isaface view ofgasaw. with my .invention associated therewith,and/Figs. 2

and 3 are cross-sections On the lines m, w and y, y respectively,in-Fig. 1.

Referring to the drawings, l designates an arbor, which is screwed ontoor otherwise suitably carried by a shaft (not. showii') and which is 2an ordinary type of rotary saw, preferably threaded upon the arbor, asshown.

The arbor is provided onn its outer face with a diametrieally-disposedgroove t e arbor, and is preferably dove-tailed to adapt it to hold acomplemental or correspondingly shaped bar or `insert 4 against lateralre moval therefrom'.

The bar or insert 4 preferably comprises a single piece, side adjacentplaning teeth edges disposed and is provided on its outer its.ends withtrimming or in the direction of revolution which form a work planing 5,which have their cutting ofthe respective ends of the bar whenturningwith the saw in making a eut. Vhenf the saw is mounted on thearbor the ends of the bar et preferably abut against the inner peripheryof thesaw opening, or may thread into such opening, as shown in Fig. 2,if desired, thus securelyloeking the bar against movement withinthearbor.

It is evident that this provides a very simple and inexpensive means ofrigidly secur-` ing the planing teeth or parts to the saw arbor, andenables the same to be easily and quickly removed when dull or broken orfor other reasons `and another one substituted therefor, as to remove abar 4 itis only necessary to remove the saw from its arbor and thenslide the bar from its holding groove.

I wish it understood that my invention is not limited to any specificconstruction or arrangement of the parts lexcept in so far as suchlimitations are specified inthe claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,- k

l. In combination, a saw carrying arbor, means removably carriedthereby, and a saw mounted on such arbor in the plane of said means andcooperating with the arbor to rigidly hold said means.

2.'In combination, a sawcarrying arbor V'having its .-outer facegrooved, work trimming means removably mounted within such groove', anda rotary saw carried by the arbor in the radial plane of said means andco` operating with 3.
